JURY AND JURY-FRAME FOR FACILITATING ORTHOPEDIC TREATMENT.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed December 27, 1907. Serial No. 408,262.

To all whom it may concern:

Be it known that I, GUsTAvE WV. IIAAs, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State oiCalifornia, have invented certain new and useful Improvements in Juriesand Jury Frames for Facilitating Orthopedic Treatment; and I do herebydeclare the following to be a clear, full, and exact description of thesame, reference being had to the drawings forming a part of thisspecification and to the letters of reference marked thereon.

This invention relates to that class of mechanical a pliances used inthe treatment of bodily defiirmities with a view to assisting nature inbuilding up healthy and corrective tissue as Well as to assistmechanically in restoring `dislocated parts to their normal positions asa progressive process, the objects of the invention being to provide anapparatus, or so called jury, with which, not only ma mechanicaltraction be secured in practical any desired direction, but with whichde ite data as to the traction exerted may be secured for the purpose ofmaking a record to show the progress of the cure and for the purpose ofcomparing the normal With the abnormal positions oi the parts.

Further objects of the invention are to provide an apparatus which maybe adjusted for use in connection with a chair of ordinary constructionor in connection with supplorting appliances which are available in t eaverage household, thereby overcomingoneof the chief obstacles to theuse of apparatus oi this character as they have heretofore required anexpensive outfit w which could only be afforded in institutions equippedfor the special treatment of deiormities.

Referring to the accompanying drawings-Figure l is a perspective view ofa jury and jury frame embodying the resent improvement. Fig. 2 is adetail o" one of the clam s for the front standards. Fig. 3 is a detaiof one of the clamps for the rear standards. Fig. 4 is a detail of thesling in which the chin and occiput rest and its flexible supports. Fig.5 is a detail oi one of the shoulder or arm pit tractors.

Like letters of reference in the several figures indicate the sameparts.

While the jury of the present invention might be supported from hooks orother suitable appliances fastened in the permanent structure of abuilding or from any preferred type of frame, the frame which forms apart of the present jury is one especially adapted to it and providesfor a variation of adjustment not readily obtainable in connection withiixed supports, or in connection with frames such as have heretoforebeen used for supporting juries of analogous character. The frame of thepresent invention is one which is readily applied to chairs of ordinaryconstruction such, for instance, as the chair A illustrated in theaccompanying drawing. Said frame consists primarily of front telesoopingstandards B, the telesooping sections of which are held in adjustedosition by double set screw clamps B and rear telesooping standards O,the telesooping sections of which are held in relative osition bysimilar double set screw clamps 8. At their upper ends, the front andrear standards unite in an angle or cornerpiece D, the union with saidcorner piece being preferably made by screwing the ends of the standardsinto the corner piece so as to form a relatively rigid detachableconnection. The corner pieces on opposite sides are connected togetherby a horizontal bar preferably formed in three sections; E, indicatingthe end sections, and E a central tubular section into which the endsections telescope, the relative positions of the sections beingmaintained by clamp screws E2. The front standards B have at their lowerends horizontally disposed clamp arms b with set screws b for clampingthe same in position over the side edges of the seat of the chair. Therear standards C have hook shaped clamp arms c with set screws c forclamping the lower ends of said standards to the back of the chair, andin addition, said rear standards have adjustable clamp arms c2 adaptedto rest on the upper portion of the back of the chair so as to limit orprevent any downward movement ol the standards when weight is applied tothe top of the frame. This construction of jury frame permits of apractically universal adjustment of the parts to iit chairs of dii-Jferent dimensions and inasmuch as the standards themselves maj,T bereadily bowed to a limited degree, it becomes possible to arrange the'frame in a symmetrical form with the front and rear standardsconverging while at opposite sides of the chair they diverge at the toso as to form a wide top to permit of latera traction being exerted tocorrect lateral deformities and to a'dord greater comfort to the patientby making the support or jury in hammock form.

The jury used in connection with the frame described consists oftraction elements for the head and shoulders although other elements maybe added if so desired. As shown, the sling adapted to support the headby passing under the chin and occiput, is preferably formed of leatheror like material which will not be disagreeable when brought in contactwith the patients skin and is of circular or oval form with a centralopening and a transverse cut from the central opening to the peripheryat one side. This construction provides front and rear portions G Grespectively, and separated ends at one side provided with snap hooks g;while the opposite side is provided with a ring g', said snap hooks andring being adapted to cooperate with corresponding hooks and ring on thelower ends of iiexible connections I. The iiexible connections arepreferably in the form of chains, the length of which may be readilyadjusted, iirst, for rough adjustment by simply doubling the chain orproviding suitable open links therein which may be hooked into otherlinks to shorten or lengthen the same, and, secondly, for iineadjustment by turn-buckles J, The upper ends of thegflexible connectionsare secured by snap hooks or equivalent fasteners to the depending screweyes K in the corner pieces of the frame, and at an intermediate pointin each of the iiexible connections there is interposed a spring balanceWeighing scale L, whereby the traction on either or both sides may bereadily determined for the purpose of making a record or for indicatingthe tractive force necessary for restoring the parts to normal position.The loops or slings through which the arms are passed to support theshoulders, are preferably formed of hose pipe covered with leather as atM and with chains M passed throughv the hose pipe. A ring'and snap hookattachment M2 is provided between the chain and the lower end of aflexible, preferably a chain, support N adapted to extend up to thecross bar at the top of the frame. The attachment between the cross barand the suspension chain or connection is conveniently formed by a ringand sn-ap hook N whereby the position of the shoulder supports or slingsmay be adjusted horizontally, provision for vertical adjustment beingprovided as in the former instance, by the Aadjustable chain N and aturn-buckle N2. In each of the shoulder tractors there ,is also provideda spring balance scale O ln the use of the apparatus, the patients headis supported and the desired tractive pressure exerted thereon withoutexerting pressure on the sides of the head, thus the patients ears areleft entirely free and inas` much as the supporting connection extendsupwardly and outwardly, the lateral position of thel head may beregulated by shortening one or the other of the connections or byoffsetting one or both of the shoulder supports in the oppositedirection, the tendency to lateral curvature of the spine, for instance,may be corrected 5 in other words, instead of depending upon the weightof the lower portion of the patients body to straighten out the deformedparts, positive pressure or traction in the proper' direction toaccomplish this end may be exerted through the adjustment of the severalparts of the apparatus.

`It will be particularly noted that the shoulder supports may beadjusted to any position along the top rod of the frame, thus they maybe made to converge toward the point of support, or diverge, or both belocated nearer one end than the other and so too the supports for thehead sling may be connected with the frame either at the corners asshown or one or both of said supporting connections may be secured torings or other devices Vsuch as indicated at P, located on the bars ofthe frame to secure traction in the desired direction to meet theparticular requirements of the case being treated.

By the employment of spring balance scales each having its own indicatoran exact determination may be made of the traction exerted at any timeduring the course of the treatment, and by keeping an accurate record,not only may the apparatus be quickly and uniformly adjusted for eachpatient in succession, without depending upon the inaccurate andunreliable data furnished by the patients themselves, but the tractionto secure progressive results or movement of the parts, may beaccurately predetermined and the apparatus adjusted accordingly withoutconsulting the patient and in many instances without the patients evenbeing aware of the fact that the traction is being increased from timeto time or at successive treatments.

The apparatus as a whole is well adapted for being shipped in smallcompass, inasmuch as theseveral members constituting the frame and jurymay be readily separated from each other and packed for storage orshipment; thus an invalid undergoing a course of treatment, may have theapparatus shipped from place to place should the necessity for travelingarise and thereby continue a course of treatment under practicallyuniform conditions.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In an apparatus for orthopedic treatment, the combination with al'rame embodyingpfrontand rear laterally divergent standards havingclamps at their lower ends for cooperation with a chair, a cross bar,corner pieces with which the upper divergent ends offthe standards andthe cross bar are removably connected, and a head supporting slingconnected with said cross bar at widely separated points whereby lateralmovement of the` sling is controlled.

2. In an apparatus for orthopedic treatment, a `ury frame embodyingfront and rear standards formed of telescoping sections and havingclamps at their lower ends `for cooperation with a chair, corner piecesconnecting the front and rear standards and a telescopic cross rodconnecting the corner pieces, whereby the height and width of the top ofthe frame may be regulated.

8. In an apparatus for orthopedic treatment, the combination with aframe embodying laterally divergent standards, and

a cross bar connecting their upper divergent ends, a head sling,separate flexible supporting means connected at each end of the slingand to the cross bar at widely separated points, a spring balanceweighing scale interposed in each support intermediate its ends, twoshoulder slings, separate ilexible supporting means l'or connecting eachof said shoulder slings with the cross bar and a spring balance weighingscale interposed in each of said shoulder sling supports intermediateits ends.

4. In an apparatus for orthopedic treatment, a head sling adapted tosupport the head from the chin and occiput, formed of pliant materialand having a central openinor and a radial cut at one side from thecentral opening to the periphery, and suspension devices secured to thetwo ends at the sides of the radial cut and to the outer edge oppositesaid radial cut.
